Beckhoff BK5120 Bus Coupler

The bus coupler, also known as fieldbus coupler, communication coupler or coupling module, with type number BK5120 from Beckhoff is an electronic module for data communication that performs coupling functions as a mechanical attachment part in automation systems. It has dimensions of 7 x 5 x 10 cm and weighs 0.2 kg. Bus couplers act as an interface between fieldbus systems such as CANopen and the higher-level control system to enable the integration of decentralized peripheral devices into a central automation system. Typical applications are found in industrial automation for networking sensors and actuators, in mechanical engineering for connecting decentralized peripherals to central control units, and in building automation for efficient data transmission.
